Check Digit Verification of cas no

The CAS Registry Mumber 100201-03-4 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,0,0,2,0 and 1 respectively; the second part has 2 digits, 0 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 100201-03:
(8*1)+(7*0)+(6*0)+(5*2)+(4*0)+(3*1)+(2*0)+(1*3)=24
24 % 10 = 4
So 100201-03-4 is a valid CAS Registry Number.

4-NITROPYROCATECHOL ETHERS AS POSSIBLE PHOTOAFFINITY LABELS. PHOTOCHEMICAL REACTIONS OF 4-NITROPYROCATECHOL ETHERS OF BIOLOGICALLY ACTIVE COMPOUNDS

Castello, A.,Cervello, J.,Marquet, J.,Moreno-Manas, M.,Sirera, X.

, p. 4073 - 4082 (2007/10/02)

The photochemical reactions of O- and N-(2-methoxy-4-nitro)phenoxyalkyl derivatives of estrone and of the antibiotic cycloheximide with methylamine afford clean substitutions of the methoxy group.From these experiments it is inferred that 2-methoxy-4-nitrophenyl ethers can be good photoaffinity labels.
